煤矿矿区废水的人工湿地治理模式初探

摘要

According to the source , mine drainage included oxidation-leaching waste water , mine water , coal-washing water and domestic sewage .4 treating models of wetland buffer , converge wetland , flocculant +constructed wetland , construc-ted wetland were proposed to provide a economical and environmental prospect treating the mine drainage .%人工湿地是一个特殊的生态系统,利用人工湿地处理废水技术是一种新型的污水处理技术. 笔者根据废水来源将煤矿废水分为煤矸石淋滤水、矿坑水、洗煤水和生活用水4类,并针对其特点提出了缓冲湿地、"汇"湿地、絮凝剂+纯人工湿地、纯人工湿地等相应的治理模式,以期为今后煤矿废水的综合治理提供技术支撑.
